Naturgesch., 1: 146. | | Common Name: | Yellow-crowned Brush-tailed Rat | | Type Locality: | Brazil, Mato Grosso, Río Guaporé. | | Distribution: | E Bolivia and E Peru, SW to NC Brazil, S Venezuela, adjacent Colombia. | | Status: | IUCN – Lower Risk (nt). | | Comments: | Patton and Emmons (1985) recognized 2 subspecies (bistriata and orinoci) and synonymized villosus in I. b. bistriata. Listed as bistriatus by Corbet and Hill (1991:206). The sequence analyses of da Silva and Patton (1993) and Patton et al. (2000) identified two geographic and taxonomic forms within bistriata.
